        通風系統中風管和風閥操作注意事項

        來源:http://www.boursomarket.com 日期:2020-10-19 發布人:gaoshitongferng

        在安裝算量中,有一個項目為暖通,其中通風系統是其中很重要的一環。以通風系統說一下操作的方法及注意事項。
        In the installation calculation, there is a project for HVAC, in which ventilation system is a very important part. With the ventilation system to say the operation method and precautions.
        首先通風系統在安裝算量中有兩種作法,一種是描圖方式,一種是轉化方式。這次針對性說一下轉化方式的應用。
        First of all, there are two methods in installation calculation of ventilation system, one is drawing mode, the other is conversion mode. This time, we will talk about the application of transformation mode.
        本文主要強調通風系統中風管和風閥操作注意事項:
        This paper mainly emphasizes the precautions for the operation of air duct and air valve in ventilation system
        一、風管的識別
        1、 Identification of air duct
        對于風管的轉化之前,有一個內容必須要先明確,那就是關于風管的標高。用高度調整命令查看時,有時顯示出來的結果不一樣。那是因為,管線和管道的標高就是線或管的標高,平時再說管道多高時,就是把管道看成一根線。而如果做風管,那在表示標高時,方法就有些不同。要說風管管底標高,還是標高,還是頂標高。所以在風管之前,要看清圖紙上的風管將來是上平齊,還是下平齊,還是齊,那相對應的調整管底標高,標高和頂標高。(此外,在做風管轉化時,也要針對性的要使用對應的一種)。

        Before the conversion of duct, there is a content that must be clear first, that is, the elevation of duct. When viewing with the height adjustment command, sometimes the results displayed are different. That is because the elevation of the pipeline and the pipeline is the elevation of the center of the line or pipe. When we talk about the height of the pipeline, we regard the pipeline as a line. However, if the air duct is used, the method for representing the elevation is somewhat different. The bottom elevation, the center elevation and the top elevation of the duct should be mentioned. Therefore, before the air duct, it is necessary to see whether the air duct on the drawing will be flush at the top, at the bottom, or at the bottom, or on the center, and adjust the bottom elevation, center elevation and top elevation of the duct accordingly. (in addition, when doing duct conversion, we should also use the corresponding one).
        那現在要做好風管轉化,這一步要輸入好以下方面:一是風管的材質,二是風管的壁厚,三是風管的接口型式,四是風管的保溫厚度。這些參數更好看一下說明,如果沒有的話參考05N4-3的相關規定。
        Now to do a good job in the conversion of air duct, the following aspects should be input: first, the material of the air duct; second, the wall thickness of the air duct; third, the interface type of the air duct; fourth, the insulation thickness of the air duct. It is better to read the description of these parameters, if not, refer to the relevant provisions of 05n4-3.
        二、風閥的繪制及注意事項
        2、 Drawing of air valve and matters needing attention
        關于風閥可以用轉化,也可以直接繪制,方法可以參考轉化設備。這里說一下風閥中比較特殊的內容。在管道里面,閥門是不扣減管道長度的,但在風管里面,風閥是要扣減掉風管的長度的,對于不同的風閥類型,有不同的扣減方法。如下圖所示,有的是風管寬度不論什么值,風閥只扣一個固定值;有的是風管寬度論什么值,風閥長度扣固定加上風管的高度(或半徑);還有一種情況,風管的寬度與風閥的長度有一個對應關系。我們可以根據具體的說明來選擇不同的風閥類別。
        The air valve can be converted or drawn directly. The method can refer to the conversion equipment. Here is a special part of the air valve. In the pipeline specialty, the valve does not deduct the length of the pipe, but in the air pipe, the air valve should deduct the length of the air pipe. There are different deduction methods for different types of air valve. As shown in the figure below, in some cases, no matter what the width of the air duct is, the air valve is only fixed with a fixed value; in some cases, the length of the air valve is fixed plus the height (or radius) of the air duct; in another case, there is a corresponding relationship between the width of the air duct and the length of the air valve. We can select different types of air valves according to the specific instructions. 上一篇:濟南酒店廚房排煙罩是種類是什么嗎?
